* Loo 1 To all whom it may concern: Be it known that I, ODIN SUNDLY, aciti- Zen of the United States, residing at Deer Park, in the county ofSt. CroiX, State of Wisconsin, have invented certain new and usefulImprovements in Locks; and I do hereby declare the following to be afull,

clear, and exact description of the invention,

such as will enable others skilled in the art to which it appertains tomake and use the same.

This invention relates to a lock.

An object of the invention. is to provide a lock which will be durableand eliicient in use and in which provision is made for the alterationof the parts in such manner that they may be changed to be operated by anumber of different keys. v

A further object of the invention is to so construct the device that thelocking means will be automatically operated when inserted in the bodyof the lock.

With these and other objects in view, such as will appear as thedescription progresses, my invention comprises the combination andarrangement of parts as set forth in and falling within the scope of theappended claim.

Referring to the drawing: Figure 1 is a perspective view of the device.Fig. 2 is a longitudinal sectional view. Fig. 3 is a sec tion on line 33of Fig. 2. Fig. 4 is a detail of the locking core detached.

Referring to the drawing wherein likeparts are indicated by likecharacters throughout the several views :My device comprises a bodyportion 1 made of suitable metal and having a longitudinally extendinghole 2 therethrough which terminates at the upper end in an elongatedslot 3, the said slot being normally covered by means of a hinged plate4.

On one side of the body portion ljis formed a pair of outwardlyextending ears 5 between which is pivoted an varcuate shackle 6 on abolt 7 In the end of this shackle 6 is formed a circular hole 8. The endof this shackle passes through an elongated slot 9 in one face of themember 1 and the hole 8 is brought into registration with the hole inthe body portion 1. However, the diameter of this hole 8 is less thanthe diameter of the hole 2 for a purpose to be hereinafter described. Inorder that this shackle 6 may be locked in the body portion 1, I haveprovided a plunger 10 which has a barrel Specification of LettersPatent. I Patented Dec. 19, 1916. Application filed October 5,1914.Serial No. 86 5,167.

portionon one end thereof, the diameter Adjacent this barrel 11 is areduced portion 12, the diameterof which is equal ,to the diameter ofthe hole 8 in the shackle 6 and 1 than thediameter of the hole 8.Secured to theshank 13 adjacent the head 14 is a being equal to thediameter of the hole 2.

pair of diverging leaf springs 15 which terminate adjacent the end ofthe portion 12.

Secured to the barrel 11 is-an outwardly extending projection 16 which;cooperates with a notch 17 in oneside of the body portion to determinethe locking position of the bolt 10." j y In operation the free end ofthe shackle 6is placed in the slot 9 after having been passed about themember which is to be locked and the head 14 of the bolt 10 is passedthrough the end of the hole-2and through the hole 8 in the shackle 6,the bolt I 10 is then pushed inwardly and the springs 15 are pressedagainst the shank 13 by the free end of the shackle'6, the barrel 11 isthen rotated until the projection 16 registers with the notch 17 atwhich time further movement of the bolt inwardly causes the ends of thesprings 15 to pass beyond the free end of the shackle 6, at which timethe ends of the springs fiy outwardly and bear against the inner face ofthe said shackle so that when in this position the said bolt 10 may notbe removed without pushing the free ends of the springs inwardly towardthe shank 13 and thus the shackle will be held in its locked position.

The head 14 is provided with a plurality of notches 18 which are adaptedto 'co6p erate with projections on the key to allow the latter to bemoved over the shank 13 in a manner now to be described.

When it is desired to release the free end of the shackle 6 a suitablekey having .a hole that the key may be changed the end of the bodyportion 1 may be provided with a plurality of notches so that theprojections 16 may be engaged in different notches as the occasionarises.

It may be thus seen that I have provide readily altered so as tonecessitate the using of different keys.

lVhile I have illustrated and described a particular embodiment of myinvention, I have merely done so for the sake of convenience and I donot wish to be limited to that particular embodiment as it'is obviousthat numerous changes may be made in the details of construction thereofwithout in any way departing from the spirit of the invention orexceeding the scope of the appended claim.

What is claimed is In a device of the class described, a casing having alongitudinally extending hole therethrough, a, shackle pivotally securedto one face of said casing, the said casing having a slot inthe saidface through Which the free end of the shackle passes, said free end ofthe shackle having a hole therein registering with the hole in the bodyportion but of lesser diameter, a bolt arranged to be inserted in thehole in the body por tion and having a reduced portion on one endthereof adapted to fit the hole in the end of the shackle, said reducedportion carrying a further reduced portion forming a shank, ahead on theend of said shank, a plurality of leaf springs secured to said bolt andarranged to lie beneath said head with their ends housed behind saidreduced portion in unlocking position, a projection on the said bolt,and a notch in the said casing arranged to cooperate with saidprojection to determine the locking position of the said bolt.

In testimony whereof, I affix my signature, in the Presence of twowitnesses.
